Answer:
commutative property
Step-by-step explanation:
You switched the numbers inside the parenthesis, which in this case is 5 and -5.
What you need to do is that you plug p=3 into the expression [(5.4p+5)+(8+3.2p)]/2 and you have:
[(5.4*3+5)+(8+3.2*3)]/2
= (21.2+ 17.6)/2
= 38.8/2
= 19.4
The average of the two boys' points is p=3 is 19.4 points~

Answer:
-7x+6
Step-by-step explanation:
Use the distributive property.

Since 6 is negative, a negative multiplied by a negative is equal to a positive. Change the negative in front of the 6 into a positive.
-7x + 6
